ABSTRACT:
Apparatus (10) and method to separate a loose mass formed by elements or materials (11) of different sizes, such as woody strands or wafers, comprising a separation chamber (13) into which the mass is inserted, a plurality of riddling rolls (16), mounted inside the chamber (13) rotating on axes of rotation parallel to each other and lying sybstantially on a same plane (X). Each of the riddling rolls (16) comprises a plurality of riddling elements (20), each of which is substantially square in shape, so as to form four cusps (22) in correspondence with the four tips of the square. The riddling elements (20) are adjacent to each other so that the cusps (22) form a plurality of grooves (24), and the riddling rolls (16) are axially staggered therebetween so that the cusps (22) of each roll (16) are constantly inserted, more or less deeply into the corresponding grooves (24) of the adjacent riddling roll (16), so as to define discharge apertures (25) with an alternated profile.
